Tube earthing clamps for lightning protection, also known as pipe clamps or downspout clips, are essential components for connecting down conductors to metallic pipes or downspouts in lightning protection systems. These clamps are available in various configurations to accommodate different pipe diameters, typically ranging from 3/8" to 4" for pipe clamps, and 100mm to 120mm for downspout clips. They are manufactured from materials such as hot-dip galvanised steel (St), stainless steel (VA, grade 304), copper (Cu), and aluminium (Alu), ensuring corrosion resistance and reliable electrical continuity. The 303 DIN series pipe clamps are designed for direct pipe mounting, while the 301 series downspout clips offer adjustable or fixed beading options for secure attachment to gutters and downspouts.

These clamps are primarily used in lightning protection and earthing systems for residential, commercial, and industrial buildings. They are installed on downpipes, gutters, and other metallic pipework to ensure a low-impedance path for lightning currents to the ground. Common applications include roof drainage systems, rainwater pipes, and metal piping in building services. They are also used in industrial environments where metallic structures require bonding to the main earthing system, such as in chemical plants, refineries, and data centres.

The tube earthing clamps comply with international standards such as IEC 62305 for lightning protection and DIN EN ISO 1461 for hot-dip galvanised coatings. The 303 DIN series pipe clamps are designed to fit standard pipe sizes according to DIN EN 10255, while the 301 series downspout clips are compatible with standard gutter profiles. These clamps are compatible with a wide range of OBO Bettermann lightning protection components, including down conductors, earthing rods, and test joints, ensuring a complete and reliable system.

At Electric Automation Network, we offer a comprehensive range of OBO Bettermann tube earthing clamps for lightning protection, with real-time pricing and availability.
